## Glean

Glean addresses a problem most enterprises hit after their first wave of AI adoption: models are powerful but isolated from the context of the business. The platform builds an enterprise context layer by indexing and understanding content across the tools a company already runs on, then uses that grounding to improve both answer quality and efficiency. Because fewer irrelevant tokens need to be sent to a model, the same question costs less to serve.

The product surface spans four areas: enterprise search, an AI assistant for everyday work, an agent platform for automating long-running processes, and Glean Protect for security and governance. Administrators also get model routing and an AI gateway, letting them decide which models handle which requests without rebuilding integrations. Everything inherits the access permissions of the source systems, so answers stay within each employee's existing rights.

Glean serves large organisations across finance, healthcare, retail, technology, and government, with published customers including Booking.com, Zillow, and Ericsson. It holds SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, GDPR, and TX-RAMP Level 2 attestations, and reports 275+ connectors, 40+ supported language models, and 99.9%+ uptime on core services.

**Pricing & Plans:** Contact for pricing. Glean is licensed to organisations based on seats, connectors, and deployment scope, and is evaluated through a demo rather than self-serve purchase.

- **Permission-aware enterprise search:** Ask a question in plain language and get a cited answer assembled from documents, tickets, wikis, and messages across every connected system, with permissions respected.
- **Agent builder and orchestration:** Reusable agents handle multi-step workflows such as onboarding, account research, or incident follow-up by orchestrating actions across business apps.
- **Model routing and AI gateway:** Glean automatically picks and routes requests to the right model and reasoning level, giving teams access to 40+ LLMs through a single governed gateway.
- **Grounded content and analysis:** Draft on-brand documents, summarise meetings, analyse data, and create content grounded in company context rather than generic model knowledge.
- **Governance and observability:** Administrators get usage controls, spend visibility, audit logging, and compliance-ready governance for every AI interaction.

**Strengths:** Answers cite source systems and inherit their permissions, which removes the main blocker to enterprise-wide rollout; One platform covers search, assistant, and agents instead of three separate vendors; Model routing and token efficiency directly reduce the cost per AI query at scale; 275+ pre-built connectors shorten integration work considerably

**Limitations:** Enterprise pricing is quote-based, so budget planning requires a sales conversation; Full value depends on connecting many internal data sources, which takes IT effort; Smallest teams may find the platform more than they need

## HighlightGPT

HighlightGPT exists for the moment when a sentence on a webpage does not quite make sense and you do not want to break your reading flow to open a separate chat tab. You highlight the difficult passage and the extension sends it, together with a configurable amount of surrounding page text, to an OpenAI model that returns a plain-language explanation. Because the surrounding paragraph, heading and nearby argument are included, the answer tends to reflect what that sentence means in this specific article rather than a generic dictionary definition.

The extension exposes three levels of context so you can trade accuracy against cost: higher values pull in more of the page and give richer answers, lower values keep requests small and cheap. If a selection is too large for the model's request limit, HighlightGPT automatically reduces how much page content it ingests so the request still goes through. Double-click highlights are deliberately ignored, which prevents accidental triggers while you are simply selecting text to copy.

Setup is minimal but does require an OpenAI API key, and every explanation you generate is billed against that key. The project is a small, single-developer tool published under the name Sacrosaunt, and it upgraded its underlying model to GPT-4o in version 1.1.3. It is best understood as a focused reading aid rather than a full AI assistant suite.

**Pricing & Plans:** The extension itself is free to install, but it is not usable without your own OpenAI API key. You pay OpenAI directly for the tokens each explanation consumes, and larger context settings increase that cost. There is no separate subscription sold inside the extension.

- **In-place explanations:** Highlight a confusing sentence and receive a short explanation without leaving the page or opening another tab.
- **Three context levels:** Choose how much surrounding page text is sent along with your selection to balance answer quality against API cost.
- **Automatic request trimming:** When a selection plus page context exceeds the request size limit, the extension automatically lowers how much page content it ingests.
- **Double-click protection:** Accidental highlights created by double-clicking are ignored, so the tool only fires when you deliberately select text.
- **Bring-your-own-key design:** Runs against your personal OpenAI API key, keeping you in control of model choice, quota and spend.

**Strengths:** Explanations use surrounding page text, so answers match the article rather than a generic definition; No context switching — you stay on the page you are reading; Adjustable context depth lets you control how much you spend per explanation; Simple, single-purpose design with automatic handling of oversized requests

**Limitations:** Requires your own OpenAI API key, which adds setup friction for non-technical users; High context settings can consume your OpenAI quota quickly; Small user base and a narrow feature set — it explains text and little else
